918 springs How capable are the Comp Cams 918 beehives?
Are they good enough to handle a 230/236 .590/.598 cam?
I'm thinking they're not quite enough spring, but I'd like to know what the experts think.

if you want peace of mind, throw in a set of duals w/ Ti retainers. you can pick up a set of PRC's or PP duals with springs/seats/titanium retainers/seals for around 280$.... but i do believe in overkill 
with that limiter, and that cam, i wouldnt put anything even questionably in-capable in there, its just too cheap for some sho-nuff springs.

i guess i've been underestimating those badboys! i've been researching hardcore for a new valvetrain setup for the past week or so. i have a lifter thats speaking a little too loud for comfort and i'm going to change out the whole valvetrain (doing a cam this summer). i'm eyeballing the PRC dual kit myself.

The 918's are waaaaaaaaaaayyyyyy more spring than you can imagine. Coil bind isn't until .750 or so, and i wouldn't worry about high ramp rates. The 918s are a very very nice spring for the money and can handle most cams on the market today. The only reason i went to a dual spring is for peace of mind and not worrying about broke valvesprings at 7300 rpms.

I have no prob's w/ 918's on a TR224 on the Formula. Had them for about 10k miles and no issues at all. I would put them on the Z06 with a bigger cam with no 2nd thoughts as well!
